I am considering upgrading the tires on my MGA. I've been running Vredestein street radials (185/70X15) on 5.5" wide 72 spoke wire wheels. If the budget allows, I plan to switch to bolt-on Minilites that are available in 15" X 6" wide. Then I'd be able to use a higher performance tire.

I see that many use Hoosiers - how long do they typically last?

Would a high performance DOT radial be 'legal' for VRG? The VRG rules state that we follow the SVRA tire rules. The SVRA tire rules state "Any Treaded, DOT approved Tires with a UTQG of 100 or greater with appropriate Speed Rating and a minimum Aspect Ratio of 60"http://www.svra.com/wp-content/uploads/ ... s_4.16.pdf

I see the rules page has been updated. Looks like a lot of good work has been done! All hail the rules makers! I really like the V (vintage) and H (historic) designations.

Question, (ah there is always one in the crowd...) the tire rules lists specific tires (often in specific sizes). That tends to leave out a lot more than it includes. One example: a certain tire brand/model might be listed in a 14" size only. That leaves me out (MGA with 15" wheels). And, my bigger concern is that tires seem to be a constantly changing item. (pun?) By listing specific brands/models of tires it seems like the rules makers will have to update the list frequently as tire brands/models come & go. Might it not be easier to delineate the specifications - size/aspect ratio, treadedness, compound/wear rating, etc)?

Believe me, tires are the biggest headache for rules-makers! A huge headache! If there's a specific tire that you want us to consider for your car, e-mail that info to me and the Eligibility Committee will review it and make a decision. Offhand I can't think of a Hoosier that's available in 15" that would be appropriate for your car, that's not already on the list -- but maybe you know of something I don't. E-mail me.

In general ... well, sometime we should talk over a beer about tire rules in vintage racing. Like most relationships, "it's complicated." Trust me, I WISH we could just describe the parameters and not have to list each tire by manufacturer and name. It just hasn't work very well doing it that way in the past, there are too many loopholes in whatever parameters we could write. So the only way I know of, is to deal with each specific brand & tire model, in each specific size, for each specific class of car. And yes, that means we have to try to keep tabs on any new tire that come out, which is difficult. Frankly the best source of information on new tires is you, our members and entrants -- when you see a new tire, let us know so we can check it out. This may come as a shock, but the tire manufacturers don't call VRG World Headquarters every time they introduce a new tire. I wish they did. I'm just not on their speed-dial list.
